The name of a Windows Store app can be changed, and it’s quite easy to do. Here I’ll walk you through the steps and show you how it’s done.
We have a JayLabs-app (JayLabs is our playground account where we publish internal apps that are not showcase quality) called Rater that we’d like to rename to Vote Collector. What we want to see is this flow:
An update is available:
The app has after the update a new name:
And searching for the app in the Store shows the new name:
To accomplish the name change we have to
1. Reserve the new name
2. Change the app name
3. Change the package name
As with the initial release of a Windows Store app – the name has to be reserved. You can read all about app naming in the docs. This screenshot shows the after-result of this little exercise – after the name change has taken place. As you can see the current name of the app cannot be deleted, but the other can.
The name of the app that will appear on the tile is called ‘display name’ and lives under the Application UI tab of the app manifest.
The name of the package, the name that appears in the Store, is called ‘package display name’ and lives under the Packaging tab.
Changing the name of an app can be done, but requires the new name to be reserved. After the app has been renamed and published as the new name, the old name can be deleted and hence released to the world.
Happy (re-)naming

Hi, how can I change package name? (3 step)
In Visual Studio only I can change the package display name, but if i change the package name field, it says me an error
Hi Carlos,
confusing title on step 3, sorry. You’re only supposed to change the package name, that’s enough!
Ok, thanks. I changed only the display name and is only for Title. As you say I have to change “package display name” for change the name on the store, thanks a lot.
